Dennis Trident III (DM5000)

SBS Transit

In 1998, Singapore Bus Service (SBS) placed an order for 20 units of Dennis Trident III for delivery and assembly in late 1999. Touted as Singapore's first zero step, fully accessible super low floor double-decker buses, it is also the first Dennis double deck model to be introduced to Singapore roads (after a trial demonstrator of Dennis Dominator double-decker in the early 1980s).

The Dennis Trident III were similar in terms of specifications as their Hong Kong counterparts, with one exception that these buses are not wheelchair accessible for SBS. It is worth noting that the rear tag-axle has no steering capabilities, similar to its predecessor Dominator (Dragon) chassis. The buses only entered revenue service in 2001, as Dennis had to fulfil hundreds of orders placed by Hong Kong operators.

Apart from a few demonstrator buses, the majority of SBS's fleet of buses were still using plastic destination signs. In contrast, the Dennis Tridents were one of the first batches of buses in SBS fitted with electronic destination screens by Transit Media when first introduced. It also featured a re-designed 'Superbus' livery adopted by all air-conditioned double-decker buses, this time with two large forward pointing red arrows. The other bus that received the updated 'Superbus' livery was SBS 9888 Y, a Volvo B10TL Super Olympian demonstrator.

After the rebranding exercise of SBS to SBS Transit, there were some changes to the Dennis Trident buses. The 'Superbus' livery was subsequently dropped and replaced by the standard SBS Transit livery, while some electronic destination signs units were replaced by other brands such as Cool-Air and Hanover.
